What is potassium t-butoxide ?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Ambroxan which has developed particularly rapidly in recent years. Do you know about Ambroxan?

The official answer: Ambroxan is a chemical compound with a relative molecular weight of 236.34.

What’s the application of potassium t-butoxide ?

Potassium tert-butoxide, an organic compound with the molecular formula C4H9OK, is an important organic base with a higher basicity than potassium hydroxide. Due to the induction effect of (CH3)3CO- three methyl groups, it has stronger basicity and activity than other potassium alcohols, so it is a good catalyst. In addition, as a strong base, potassium tert-butoxide is widely used in chemical, pharmaceutical, pesticide and other organic synthesis, such as ester exchange, condensation, rearrangement strength, polymerization, ring opening and the production of heavy metal protic acid esters.

WHY THEY SAY TO US

United Kingdom Giles
United Kingdom Giles
Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
